Very high ( 99%) diastereofacialselectivities in aldol reactions of a chiral titanium enolate with a variety of aldehydes can be conveniently achieved. The ease of preparation of -Ti(OCHMe2)3 enolates, low cost, low toxicity, and ease of work-up make this a very useful method for synthesis of chirally pure substances.
